Check & Fix Plugin Version

Verify the installed compound-engineering plugin version matches the latest released version, and fix stale marketplace/cache state if it doesn't. Claude Code only.

Pre-resolved context

The three sections below contain pre-resolved data. Only the Plugin root path determines whether this session is Claude Code — if it contains an error sentinel, an empty value, or a literal

${CLAUDE_PLUGIN_ROOT}

string, tell the user this skill only works in Claude Code and stop. The other two sections may contain error sentinels even in valid Claude Code sessions; the decision logic below handles those cases.

Plugin root path: !

echo "${CLAUDE_PLUGIN_ROOT}" 2>/dev/null || echo '__CE_UPDATE_ROOT_FAILED__'

Latest released version: !

gh release list --repo EveryInc/compound-engineering-plugin --limit 30 --json tagName --jq '[.[] | select(.tagName | startswith("compound-engineering-v"))][0].tagName | sub("compound-engineering-v";"")' 2>/dev/null || echo '__CE_UPDATE_VERSION_FAILED__'

Cached version folder(s): !

ls "${CLAUDE_PLUGIN_ROOT}/cache/compound-engineering-plugin/compound-engineering/" 2>/dev/null || echo '__CE_UPDATE_CACHE_FAILED__'

Decision logic

1. Platform gate

If Plugin root path contains

__CE_UPDATE_ROOT_FAILED__

, a literal

${CLAUDE_PLUGIN_ROOT}

string, or is empty: tell the user this skill requires Claude Code and stop. No further action.

2. Compare versions

If Latest released version contains

__CE_UPDATE_VERSION_FAILED__

: tell the user the latest release could not be fetched (gh may be unavailable or rate-limited) and stop.

If Cached version folder(s) contains

__CE_UPDATE_CACHE_FAILED__

: no marketplace cache exists. Tell the user: "No marketplace cache found — this appears to be a local dev checkout or fresh install." and stop.

Take the latest released version and the cached folder list.

Up to date — exactly one cached folder exists AND its name matches the latest version:

• Tell the user: "compound-engineering v{version} is installed and up to date."

Out of date or corrupted — multiple cached folders exist, OR the single folder name does not match the latest version. Use the Plugin root path value from above to construct the delete path.

Clear the stale cache:

rm -rf "<plugin-root-path>/cache/compound-engineering-plugin/compound-engineering"

Tell the user:

• "compound-engineering was on v{old} but v{latest} is available."
• "Cleared the plugin cache. Now run

  /plugin marketplace update

  in this session, then restart Claude Code to pick up v{latest}."
